Card Identification Forum

I have two 1997 Collector's Edge Extreme Forerunners Terrell Owens Cards.  One has a serial number on it but the other does not as pictured.  They are the exact same cards on the front and back otherwise.  Forerunners is a subset of the main Extreme set and I only see one version of it on the TTCD  site and in the Beckett Price Guide.  I am assuming the card without the serial number is an error but wanted to see what others thought. - Thanks

Collector's Edge was know to sell complete sets after the regular release was issued.  The complete sets usually had either different SNs or no SNs.

Thanks for the info.  I am going to put the serial numbered version on the site but I'm not sure what to do about the card that is not serial numbered.  If it is a seperate version of the set, shouldn't that set be included in the database?  I have some other Collector's Edge cards from different sets with the same scenario as well.  If you or anybody else has any input on this, please let me know.  I'm fairly new to the site and really like it's concept and would like to help it be as thorough and accurate as possible because it has helped me figure out what sets several cards I have are from.
